Abstract:
ONE GRADED W-BeO nozzle insert was coated with W. The BeO reacted with the gases in the reaction zone to create unfavorable coating conditions. Several indentations in the W coating appear to have been cauused by the escape of reaction products. The W coating projects from the contour of the insert in a form resembling layers peeled from the surface. Clear crystals were formed on cooler surfaces within the reaction zone. Author
